The chief feature "of the invention consists in the structural arrangement *of the fmain separator r dehydrator unit which herein is illustrated as ofthe 'centrifugally tion included in the separator. f'Fig. Sis a transverse sectional view takenon the line 3-3 of Fig.1 and in the direction of: the arrows and illustrates: particularly 'the"ag1- tator constructionp Inthe drawing v lO including an oliset bracket portion ll and a diverging upturned supporting bowl '12. The extreme end of the bowl 12i's apertured at 13 and supported by the same is af tube 1 1: that in turn supports an annular plate 15, said plate being rigidly mounted-upon the base construction previously described, 'by means of the bolt 16 and the;nuts 17. Any other suitable 'form of mounting, however, may be utilized without. departing from the invention- Depending from the annular plate which also forms a cover for a construction hereinafter to bel described is a shell 18 having an outwardly directed lateral fiange 19, whereby the same is supported upon the annular plate 15-. Po

sitioned axially within said shell '18 is atube 20 which is connected to a pipe or'supp'ly line 21'. controlled by a valve 22. 'Hereln "the aforesaid construction is all stationarily mounted with respect to each. other. f v
